STATE-S PATENT OFFICE HOWARD MORRIS, OFTOLEDO, OHIO, ASSIGNOR TO THE AUTOMAT' MOLDING- & FOLD- ING- COMIANY, OFTOLEDO, OHIO, A CORPORATION OF OHIO MACHINE FOR HANDLING BUTTER I RINTSOriginal application filed July 8, 1930, Serial No. 466,394. Divided andthis application filed September This invention relates to machines forwrapping bars of butter, oleomargarine, or like plastic or semi-plasticmaterial, but more particularly to mechanism for conveying the barsdirectly after they have been severed the bars from one place to anotherin such manner that liability of the bars adhering to the unsevered massor slab is eliminated.

Other objects and advantages of the invention will hereinafter appear,and for purposes of illustration, but not of limitation, the inventionis shown on the accompanying drawings, in which:

Figure 1 is a side elevation partly in section of a feeding mechanismfor an article wrapping machine showing particularly the feedingmechanism, the bar elevator or conveyor, the advancing ram andassociated driving mechanism;

Figure 2 is a side elevation partly in section of the elevator andassociated parts showing the elevator in its lowered position with asevered bar or print in position to be engaged by the ram for furtheradvancing movement;

Figure 3 is an end elevation-partly in section of the cutting head; and

Figure 4 is a top plan view of the article feeding mechanism andassociated parts.

This application constitutes a division of my co-pending applicationSerial No. 466,394, filed July 8th, 1930, and entitled Article feedingmechanism. 5

The illustrated embodiment of the invention comprises a table 2 having aseries of laterallyspaced rollers 3 over which a slab S of butter,oleomargarine, or other material of similar plastic or semi-plasticnature, is advanced. Opposite sides of the slab S are engaged byparallel runs 4 of endless belts Serial No. 563,602.

5 which extend longitudinally of the table 2, and are disposed onopposite sides thereof. Spring tensioning devices 8 are utilized forholding the runs 4 of the belt 5 in engagement with opposite sides ofthe slab S. One

tion detailed description thereof is not con sidered necessary.

At the forward end of the table 2 is a cutting device 15 for severingfrom the slab S prints or bars. As shown in Fig. 3, the severing devicecomprises an inverted U-shaped frame 16, which is mounted on verticalrods 17 Attached at one end to a post 18 is a cutting wire 19, whichextends across the arms of the frame, and has one end wound about ascrew threaded bolt 20, which is secured to the frame 16.

The-cutting device 15 is vertically reciprocated by a yoke 56, whichstraddles a transverse driven shaft 25. A roller 57 on the yoke 56 ridesin a cam groove 58 formed in a wheel 59 rotatable with the shaft'25. Theyoke 56 is suitably connected to the cutting unit 15 to impart verticalreciprocatory movements thereto, the cutting head being guided initsvertical movements by guide rods 62. The cutting device 15 is timed tooperate at the period when the conveyor belts 5 are at rest. Thusapredetermined quantity of material is advanced by the feeding device,and then the feeding device is rendered inoperative, whereupon thecutting device operates to fiever the material so advanced from the slaThe prints or bars P severed'from the slab S are supported on anelevator 63, which moves downwardly into a position where a has.

ram 64 engages each bar and advances the same from the elevator along atable 65 to the wrapping mechanism (not shown). Depending from theelevator 63 and inclined forwardly therefrom is a rod 66, the movementof which is guided by a sleeve 67 secured to the machine frame. Movementis imparted to the elevator 63 by a link 68, which is pivoted to one armof a bell crank 69, the opposite arm of which is connected to a rod 70deriving its motion from a cam 71 rotatable with a transverse shaft 22.

A cardinal feature of this invention resides in the removal orseparation of the severed print or bar P from the slab S in such amanner that thebar will not stick or adhere to the unsevered mass duringits removal. Difficulty has heretofore been experienced in separating orremoving the severed print from the slab where the print is moved atright angles to the slab. This has materially interfered with theefficient operation of the machine, and has for some time been a sourceof annoyance to users of machines ofthe above type This inventionobviates the difiiculties heretofore encountered for moving the severedprint from the slab at an angle so that liability of the print stickingto the unsevered mass is eliminated as apractical matter.

It is to be understood that the above description is given by way ofillustration, and not of limitation, and numerous details ofconstruction and operation may be effected without departing from thespirit of the invention as defined in the following claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a machine of the class described, a feeder for advancing a slab ofbutter or the like, a device operable intermittently to sever apredetermined amount from said slab, an elevator to receive the severedquantity, and lever means operable to shift said elevator away from saidfeeder at an angle less than a right angle to the plane of severance ina substantially vertical direction to prevent the severed quantity fromadhering to the remainder.

2. In a machine of the class described, means for feeding a slab ofbutter or like material, means to sever a predetermined amount from saidslab, means for receiving the severed amount, and means for moving thereceiving means away from the feeding means at an angle less than aright angle to the plane of severance and in a substantially verticaldirection whereby to prevent the severed quantity from adhering to theremainder.

3. In a machine of the class described, means for feeding a slab ofbutter or like material, means to sever a predetermined amount from saidslab, means for receiving the severed amount, and means for movingHOWARD A. MORRIS.
